Pr Chart

Simple AWS SAM / TypeScript / Arc / Svelte app

Pull Request Charts

Using AWS Serverless Application Model, Svelte and TypeScript.

Code uses Arc Serverless conventions:

Layout:

Lambdas are defined under arc in package.json
Lambda code is under src/http. Shared code is src/shared (all lamdas) and /src/views (GET requests only)
Frontend code is under src/frontend. The UI is built using Svelte, a modern framework that avoids the size and slow performance of a virtual DOM. I have experience with React, Vue, Ractive, Backbone, Angular etc but have recently been working in Svelte and it seemed prudent to stick to a newer tech rather than re-learn React.
Config is under .env, which is not committed for security reasons.
public dir is mapped to static in each lambda.

On page load, the user sees stacked bar chart with the bars representing the number of pull requests that were opened and closed during that month (note this particular project has few PRs closed).
When hovering over one of the bars, the user sees a tooltip that contains the number of opened and closed pull requests for that month.
Pagination is implemented (the repo is question doesn't have enough PRs, so the tests use nodejs itself)
There's a full test suite and instructions for running the app below

I time-boxed my work on this, but I'd do these next:

Filtering for Last Month, Last 90 Days, All Time, etc.
The backend should cache GitHub responses, store them and deliver them offline.
Minor visual tweaks (consolidating labels in the charts, gradients on the bars, etc)

npm test

The app needs a GitHub auth token specific to your account.

npm start

Set up your ~/.aws/credentials and run:
